Project Pokémon Bot

In Pokemon Omega Ruby & Alpha Sapphire: Special Demo Version, you get to choose a starter for the initial mission,
evolve your starter, get the Mega Stone for your first Mega Evolution in the Special Demo Version,
defeat Team Magma & Aqua admins, and capture a Glalie International region 3DS / Steelix JP region 3DS, that will be transferred to the main game,

For subsequent missions, you'll begin the demo with the final evolution of all the starters, all holding their Mega Stones.
Accompanying you, is also the Pokemon obtained from the initial mission, that is also holding it's Mega Stone.


This page contains various for these Pokemon, as well as other unobtainable Pokemon encountered throughout this Special Demo Version, obtained by @jojo12100 & @BlackShark.

Original Thread:

Out there in the wild, exists a German Language Debugger's/Developer's Edition of Pokemon Ruby Version,
which contains many debugging tools, including Mystery Event distribution subroutines.
Using existing unmodified subroutines, a Tournament Unown can be transferred.

Working on the data discovered by The Cutting Room Floor and GlitchCity Forums, and with @BlackShark's help,
the remaining Pokemon could be transferred by doing modifications in order to activate the other subroutines,
that contains the other hidden debugging Pokemon.

Original Thread:

For a short while for the Wild Area event #14, players were able to encounter a Drilbur with Hydro Pump, exclusive to Shield 1 star raids.

While it was possible to obtain this legitimately, Game Freak is treating it as though it didn't happen, and this Drillbur cannot be used online. 
Back when the event was still ongoing, the Wild Area News was updated, and Drillbur can no longer be encountered with Hydro Pump, effectively fixing the error.
Any players that did not update their wild area news, or have already caught one, will have the Drillbur unchanged.

It is not known if this Drillbur can go into HOME (at time of writing).

For the time being, this Drillbur will be classed as illegal.

This gift was distributed to players who visited the Space Center Houston, to commemorate the 10th Anniversary of Pokémon.
The distribution ran daily from March 10 to March 19, 2006,
then distributed every weekend (Sat & Sun) from March 25 to May 14, 2006.

This Pokémon is a rare variant that is capable of Gigantamaxing, and can only be obtained via Max Raid Battles in the Wild Area.

While always available for capture (if found) in a den in the Wild Area, an event from November 15, 2019 to early January 2020 made it more commonly found in Pokémon Sword, by having it appear in dens normally not associated with it.
To be able to encounter the event variant, user's Switch must be connected to the internet, with the Mystery Gift>Get Wild Area News option used during the event period..
Alternatively user must have connected to the internet and redeemed a Mystery Gift during the event period.

This Pokémon is a rare variant that is capable of Gigantamaxing, and can only be obtained via Max Raid Battles in the Wild Area.
There's no event associated with it at time of writing.

This Pokémon is encountered at the Watchtower Lair's Den when the event item is used.

This file was hosted on Mystery Gift Servers of Pokemon X and Y, however was ultimately not released for download,
presumably because it was later distributed by the Pokemon Bank service.

Attached are the ENG, FRE, GER, ITA and SPA version of this wonder card.

This wild area event held by Sword and Shield. It made Gigantamax Snorlax the focus of the event.
For base game Pokémon Sword and Shield, without this event, there is no den that will enable players to encounter a Gigantamax Snorlax.

As per the previous events, Drednaw and Sandaconda were Sword exclusive raids, and Corviknight and Centiskorch were Shield exclusive raids. Butterfree and Snorlax can be obtained regardless of game.
Though it is important to note, host can include players of the opposite version to join in the raids.
This event ran globally from December 4th, 2019 to January 9th, 2020.
The running of this event was interrupted twice in favor of other events:
#3 Christmas 2019 (Index 03 and Index 04)
#5 New Years 2020 (Index 06)

On August 5th, 2017, around 01:37 GMT, a Marshadow test card was uploaded for testing, and quickly removed.
As per previous tests, it was likely to test if the the Serial Codes they have on hand can retrieve the card from the correct Wonder Card ID slot.
(Meaning, they're likely reserving this wonder card ID for international releases of Marshadow)

The data is identical to the upcoming Red Hot Charizard (it's used as a base, for the dummy test)

While this forme is accessible once you capture Necrozma, and gain access to the the N-Solarizer and N-Lunarizer,
and also having a Solgaleo or Lunala in your team (for the fusion process),
this forme, like Mega Evolution, cannot be maintained outside battle.

How this file was obtained, was by using NTR Codes that allowed catching of Trial Pokemon,
as this Pokemon was not meant to be captured as-is in the games.

This encounter cannot be shiny. This file will make your game save illegal.

This game was distributed to players of Pokémon Colosseum via the Japanese Bonus Disc.
The event itself was actually programmed into the Pokémon Colosseum game, as seen here with the English version of the unreleased event.

These sprites are from LGPE.

Programmed into Pokemon HeartGold & SoulSilver, Nosepass has the egg move Head Smash.
Problem is, in Generation 4, no Pokemon in the Mineral Egg Group was able to learn Head Smash,
so by extension, no one was able to pass along the move to Nosepass.

When Generation 5 came along, the move was removed from Nosepass's inheritable move list.
Despite having Aegislash being able to pass down the move in Generation 6,
this move has yet to make it back into Nosepass's inheritable move list.
 
This page hosts a Nosepass having the move Head Smash, obtained via Rage/Mimic Glitch,
by getting Ditto to learn the move then passing it down, thanks to @jojo12100.

In Pokemon Black 2 & White 2, lies the facility Pokestar Studios, which allow players to create "films",
which is done by having users battles Props (between a pair of legs and Mecha Tyranitar),
which are not traditional Pokemon.
In this page, hosts the various Opponent's & Rental Pokemon, for the various films.

All the film series have been uploaded to this page!

Original Thread:

With the release of Pokémon Crystal on the Virtual Console for 3DS, Celebi (shiny and non-shiny) can be transferred up using Pokemon Transporter,
due to the fact that VC Pokémon Crystal allows players to get the GS BALL legitimately (without hacking or glitching).

However, Pokémon Crystal was not released to the Korean 3DS's, neither in Korean (as Korean Pokémon Crystal didn't exist back in the day) nor in international languages (as in Korean 3DS never got it).

As such, the only Virtual Console games that do not have access to Celebi are the Korean versions of Generation II,
as the Korean Virtual Console titles cannot communicate with the Japanese nor International versions.

While it would be illegal, Pokémon Transporter allows the transfer of a Korean Celebi from Generation II.

This page contains a shiny and non-shiny Celebi modeled after the one caught in Ilex Forest of Pokémon Crystal.

When the player collects 20 Totem Stickers and shows it to Professor Samson Oak at Heahea Beach in Pokemon Ultra Moon,
he will give the player the Totem Raticate (Alolan).

The Pokemon itself will not have the Totem Aura. The gift cannot be shiny.
